Adam Back, CEO of Blockstream and HashCash, has said: "Nothing is above Bitcoin, no Central Bank Digital Currency, no stable coins."
He continued that: "I think that blockchains are more about permissionless, uncensorable usage and free market money. I think while it is possible and useful for some use cases, like crypto trading, to have stable coins, they inherently fall short of Bitcoin as they have custody risk, and if there is a central bank underwriting also traditional establishment interests reflected in the operation which may look unattractive to users."
